WASHER-MAKING -MACHINE.

Specification of Letters Patent.

Patented Jan. 23, 1912.

To all whom 'it may concern:

Be it known that I, MASON Gr. WORTH, a citizen of the United States, residing at New York, county of New York, State of New York, have invented certain new and useful Improvements in Washer-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a washer making machine and particularly to a construction adapted to produce a coiled lock washer.

The invention has for an object to provide a novel and improved construction of machine comprising an intermittently rotated coiling mandrel having a cutting face at its delivery end adapted to cooperate with an automatically operated cutting tool so as to continuously coil the washers and cut off a completed washer at each revolution of the mandrel, the parts being so con structed and arranged as to properly time the several operations thereof.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawing-Figure 1 is a side elevation of the machine; Fig. 2 is a top plan thereof; Fig. 3 is a vertical section on line 3-3 of Fig. 2; Fig. 4 is a similar view on line M of Fig. 2; Fig. 5 is a section on line 5-5 of Fig. 2; Fig. 6 is a like viewon line 6 6 of Fig. 2; Fig. 7 is an end elevation of the cutting face of the mandrel; Fig. 8 is a detail side elevation of the delivery end of the mandrel; and Fig. 9 is a detailof the completed washer.

Like numerals of reference refer to like parts in the several figures of the drawing.

The numeral 10 indicates the base or frame of the machine which is. provided with a bearing standard 11 in which-a coiling mandrel 12 is rotatably mounted. This mandrel has disposed about its periphery a series of coiling rollers 13 which cooperate therewith and are driven in any desired manner, for instance by a .gear l upon the mandrel meshing with a gear 15 upon each of the rollers. The mandrel 12 is provided with a driving gear 16which is intermittently rotated by means of a mutilated or intermittent gear 17 mounted on the main driving shaft 18 which is provided with a driving pulley 19.

The mandrel is'formed at its delivery end with a cutting face 20 of any desired construction, for instance a segmental extension as shown in Fig. .7. This cutting face is adapted to cooperate with a reciprocating cutting tool or punch 21 which may be driven in any desired manner, for instance from the shaft 22, which carries a pulley 23 and receives power by means of a belt 24 extending to a driving pulley 25 upon the main shaft 18. Beneath the cutting face 20, a reciprocating, anvil 26 is mounted and adapted to operate in unison with the punch to supportthe end of the mandrel during the cutting operation. This anvil may be operated in any desired manner, for instance by means of a pitman 27 carried by a crank 28 upon the driving shaft 18 as shown by dotted lines in Fig. 1. For the purpose of forming a space or gap between the ends of the coiled washer, and retaining the parts in proper posit-ion during the cutting op eration, a ratchet gear 29 is mounted upon the shaft of the mandrel and cooperates with a spring pawl 30. This pawl is ad-' rollers 34 mounted upon the base and rests I upon a'bearing roller 35 as shown in Fig. 6.

In the operation of the machine, the bar to be coiled is fed between the mandrel and coiling rollers at the end thereof adjacent the bearing standard and the successive coils as formed force those previously made. toward the delivery end ofthe -mandrel.,producing a spiral spring thereon as shown in Fig. 8. The coil at the free end ofthe man- ,drel surrounds the cutting face thereof and and governed by the tension or friction of the spring pawl upon the teeth of the ratchet wheel. If the pawl be moved into close contact with these teeth, only a very small backward movement can occur, while if the pawl have only a slight contact with the ratchet, a greater backward movement is permitted before the pawl brings the mandrel to rest. At this time, the cutting .tool descendsand cooperates with the cutting face of the mandrel, while the anvil rises beneath and contacts with the coil upon the mandrel to support the latter, holding the coil in position during the cutting operation. It will thus be seen that the invention presents a simple, efficient and economically constructed machine by which a coil may be intermittently formed and intermittently cut into the completed article during the continuous operation of the ma chine, thus obviating separate operations for cutting the spring coilinto the washer of the character shown.

Having described my invention and set forth its merits, what I. claim and desire to secure by Letters Patent is- I 1. In a washer makingmachine, the combination with an intermittently rotated mandrel, of an automatically operated cutting tool disposed. at the delivery end thereof and frictional means for retarding the reverse movement of said mandrel.
